I thought I would have Google build a sitemap for me. My ranking has gone down because of upgrading fallout in addition to going from domain.com/blog to domain.com so the thought of using Google's developer tools is of interest.
A problem is the Google site building process stops because of 404 errors. Is there a tool that locates broken links? Dreamweaver will find them on the local site but I am clueless on server-side tools.
